I'm with you, many folks seem to believe self driving cars will increase existing road capacity tenfold or something- I just don't see it. Once every car on the road is self driving they can maybe drive "too close" at speed, but overall there's still a limited amount of space on the pavement.

Now, if these self driving cars were high passenger capacity, that might have a great effect- but of course then we'd just call them a bus.

I don't think anyone really knows, but say we have cheap taxis, ride sharing, driving "too close", and far fewer accidents? There's still a limit but it should be quite a bit higher.

Trouble is the concept of induced demand, which roads enjoy in spades
